Police say robbery could be a motive in the slaying of a married couple in Southwest Houston yesterday.

The 42-year-old man and his 39-year-old wife were found bound with duct tape and shot to death in their partially ransacked home in the 11500 block of Keegan's Ridge, near West Bellfort and the Southwest Freeway. Their bodies were discovered by their 19-year-old daughter, who shared the home with them and her 11-year-old brother. Luckily, neither was at home at the time of the slaying.

In addition to running a private school bus service, the couple peddled snacks and soft drinks out of their home. Some are speculating that their killers were after the loot from that underground Kwik-E Mart.

Anyone with information in this case is urged to contact the HPD Homicide Division at 713-308-3600 or Crime Stoppers at 713-222-TIPS.
